AmbientCycleGAN for Establishing Interpretable Stochastic Object Models Based on Mathematical Phantoms and Medical Imaging Measurements

no code implementations2 Feb 2024 Xichen Xu, Wentao Chen, Weimin Zhou

Ideally, computation of task-based measures of IQ needs to account for all sources of randomness in the measurement data, including the variability in the ensemble of objects to be imaged.

Semantic Prompt for Few-Shot Image Recognition

1 code implementation CVPR 2023 Wentao Chen, Chenyang Si, Zhang Zhang, Liang Wang, Zilei Wang, Tieniu Tan

Instead of the naive exploitation of semantic information for remedying classifiers, we explore leveraging semantic information as prompts to tune the visual feature extraction network adaptively.

Cross-Domain Cross-Set Few-Shot Learning via Learning Compact and Aligned Representations

1 code implementation16 Jul 2022 Wentao Chen, Zhang Zhang, Wei Wang, Liang Wang, Zilei Wang, Tieniu Tan

Different from previous cross-domain FSL work (CD-FSL) that considers the domain shift between base and novel classes, the new problem, termed cross-domain cross-set FSL (CDSC-FSL), requires few-shot learners not only to adapt to the new domain, but also to be consistent between different domains within each novel class.

Semi-WTC: A Practical Semi-supervised Framework for Attack Categorization through Weight-Task Consistency

1 code implementation19 May 2022 Zihan Li, Wentao Chen, Zhiqing Wei, Xingqi Luo, Bing Su

In addition, to cope with new attacks in real-world deployment, we propose an Active Adaption Resampling (AAR) method, which can better discover the distribution of unseen sample data and adapt the parameters of encoder.

Safe, efficient and socially-compatible decision of automated vehicles: a case study of unsignalized intersection driving

no code implementations4 Nov 2021 Daofei Li, Ao Liu, Hao Pan, Wentao Chen

By investigating the causes of 4, 300 video clips of traffic accidents, we find that the limited dynamic visual field of drivers is one leading factor in inter-vehicle interaction accidents, especially in those involving trucks.
